Additional NMR Experimental Information
Details	THE STRUCTURE WAS DETERMINED USING TRIPLE-RESONANCE NMR SPECTROSCOPY ON 13C AND 15N LABELED MXIG N-TERMINAL DOMAIN. NOESY EXPERIMENTS PROVIDED THE INPUT DISTANCE RESTRAINTS, WHILST A LONG-RANGE HNCO EXPERIMENT INDICATED HYDROGEN BONDS. DIHEDRAL ANGLE RESTRAINTS WERE CALCULATED FROM A HNHA EXPERIMENT AND PREDICTED BY TALOSPLUS
